This is why i didn't go with caltrac's when i wore out my first set of SS Springs(was in us for 20+years!)
Calvert wants you to run there system on a stock leaf spring(DO NOT US ON SS SPRINGS which i have)
Is your stock 50+ year old leaf spring up to the task of the caltrac's.......Probably not. Caltrac's not much more money??????
lets do the math!
All prices pulled from Mancini racing sight.
Left and right SS Spring $279. Bolts on with out any other mods....................
Caltrac's $369 + there split mono leaf spring $439.....oh wait that for only one...+ $439!!!!
Grand total: SS Springs $279 + shipping
" ":Caltrac's complete $1,247
That is 4 times the money of a SS Spring.
If you have already replaced you spring with a stock or HD spring.........Then, and only then, is the CalTrac ONLY a little bit more money.
